Abstract: A method of verifying a transaction over a data communication system between a first and second correspondent through the use of a certifying authority. The certifying authority has control of a certificate's validity, which is used by at least the first correspondent. The method comprises the following steps. One of the first and second correspondents advising the certifying authority that the certificate is to be validated. The certifying authority verifies the validity of the certificate attributed to the first correspondent. The certifying authority generates implicit signature components including specific authorization information. At least one of the implicit signature components is forwarded to the first correspondent for permitting the first correspondent to generate an ephemeral private key. At least one of the implicit signature components is forwarded to the second correspondent for permitting recovery of an ephemeral public key corresponding to the ephemeral private key. The first correspondent signs a message with the ephemeral private key and forwards the message to the second correspondent. The second correspondent attempts to verify the signature using the ephemeral public key and proceeds with the transaction upon verification.

Inventor: LIU MING-HWA
IPC: F28F13/00
Filed: 2002-04-25
Granted: 2006-04-18
Abstract: A heat absorbing and radiating device includes a driving unit having communicable first fluid outlets and fourth fluid inlets, a heat-exchange unit communicating at an end with third fluid outlets of the driving unit and at another end with an inlet end of a liquid-gas confluence unit, which communicates at an outlet end with an inlet end of a liquid-gas separation chamber, while the latter communicates at an outlet end with one of two second fluid inlets of the driving unit. The driving unit is provided therein with reciprocatingly movable magnets to alternately push first and second fluids into the heat-exchange unit before them enter the fluid-gas confluence unit, so that hot air is finally released from the liquid-gas separation chamber. Since radiating fins and cooling fan are omitted, the device has reduced volume for use with a heat source in a small space, such as a CPU of a portable computer.

Abstract: Methods for determining a vibratory excitation spectrum are tailored to physical characteristics of a structure having critical elements located thereon to be subjected to vibration testing, such as a PCB to which connectors, resistors, capacitors, inductances, Integrated Circuits (IC) or Ball Grid Array components (BGA) are mounted. The physical characteristics includes a frequency response function corresponding to a testing environment temperature and defined in term of power spectral density amplitude over a global excitation frequency range for the vibratory excitation spectrum and characterized by a plurality of power spectral density amplitude peaks corresponding to a plurality of natural resonance frequencies, each being associated with respective mode shape and damping factor. The method comprises the steps of locating at least one anti-resonance frequency range extending between two main natural resonance frequencies, defining on the basis of the amplitude peaks corresponding to the main natural resonance frequencies at least two corresponding sets of amplitude peaks each including the amplitude peak associated with any other natural resonance frequency near corresponding main natural resonance frequency included in the corresponding set, and defining from the sets of amplitude peaks at least two spectral profile sections associated with corresponding frequency ranges. Each spectral profile section is expressed as power spectral density amplitude according to the mode shape and damping factor associated with corresponding main and other natural resonance frequencies and to the location of said critical elements, to form a vibratory excitation spectrum capable of maximizing vibration power transfer to the critical elements of the structure to be subjected to vibration at the testing environment temperature.
